Yes.
Because the oil is less dense then the water.
no
Ice is less dense than water
Vegetable oil floats on water because it is less dense than water. Density is the mass of a substance divided by its volume. Since the mass of vegetable oil is less than the same volume of water, it displaces less water and floats on top.
It makes the oil bubble and could make an explosion.
A wooden block can be less dense than water.
b/c you're less dense than the water (likely due to the gas in your lungs).
If more dense, it will sink when put into water; if less dense it floats.
Oil IS already less dense than water.
No. Ice is less dense than water. Because ice is less dense it displaces less water and floats. Water is most dense at 4o C. any change in temperature, either up or down, lowers the density.
Easy, put a fruit in water and if it floats it is less dense than water.
No, it is more dense. If it were less dense it would float.
